Abstract
This paper investigates the performance of joints produced by ultrasonic insertion and plastic injection moulding processes. The metal insert and thermoplastic test specimen, which need to be joined, are prepared as per standards. Ultrasonic insertion process is optimized through response surface methodology (RSM). The experiments are conducted, and joints are produced for optimum inserting conditions. Similarly, the metal insert and thermoplastic part are joined using plastic injection moulding process. The pull-out strength and stripping torque of joints obtained from pre, post-moulding processes are measured using tensile testing and torque testing facilities then compared. The comparative results show that ultrasonically inserted joint yields better outcomes than joints produced by pre-moulding process.
